SimpleTransformers错误: VersionConflict: tokenizers==0.9.4？我该怎么解决这个问题？

Question

我正试图从google的网站上执行简单变压器示例。

示例：

from simpletransformers.classification import ClassificationModel, ClassificationArgs
import pandas as pd
import logging


logging.basicConfig(level=logging.INFO)
transformers_logger = logging.getLogger("transformers")
transformers_logger.setLevel(logging.WARNING)

# Preparing train data
train_data = [
    ["Aragorn was the heir of Isildur", 1],
    ["Frodo was the heir of Isildur", 0],
]
train_df = pd.DataFrame(train_data)
train_df.columns = ["text", "labels"]

# Preparing eval data
eval_data = [
    ["Theoden was the king of Rohan", 1],
    ["Merry was the king of Rohan", 0],
]
eval_df = pd.DataFrame(eval_data)
eval_df.columns = ["text", "labels"]

# Optional model configuration
model_args = ClassificationArgs(num_train_epochs=1)

# Create a ClassificationModel
model = ClassificationModel(
    "roberta", "roberta-base", args=model_args
)

# Train the model
model.train_model(train_df)

# Evaluate the model
result, model_outputs, wrong_predictions = model.eval_model(eval_df)

# Make predictions with the model
predictions, raw_outputs = model.predict(["Sam was a Wizard"])

但它给了我以下错误：

VersionConflict: tokenizers==0.9.4是这个模块正常运行所必需的，但是找到了tokenizers==0.10.0。尝试: pip安装变压器-U或pip安装-e '.dev‘如果您正在使用git

我已经尝试过!pip install transformers -U，甚至!pip install tokenizers==0.9.4，但是仍然给出了同样的错误。我以前执行过这段代码，它的工作非常有趣，但是现在它给出了前面提到的错误。

Answer 1

我把这个放在这里，以防有人面临同样的问题。我是由造物主自己帮助的。

解决方案:例如，在Colab中安装简单变压器之前安装tokenizers==0.9.4；!pip安装tokenizers==0.9.4 !pip安装简单变压器

Answer 2

如上所述，我认为您基本上需要的是!pip install tokenizers==0.9.4，它将卸载tokenizers-0.10.0并安装tokenizers-0.9.4。
